GRAIN-DOOR.

Patented Oct, 21,- 1919.

Application filed December 22, 1917. seria ivo. 208,442.

To all whom it may concern:

Be it known that I, BEvILL N. Van'- I woR'rH, a citizen of the UnitedStates of grain doors, particularly those employed on a railway.box-car, and the objectof -my improvement is to furnish a doorwhlch willbe movable longitudinally along the outer face of a car, and which willbe movable to shift into or out of a door-casing to a position for suchlongitudinal movements,

without obstructing the door-opening and without in any way modifyingthe interior walls of the car; Other improvements. will be morespecifically described, pointed out in the "appended claims, and shownin the drawings, in which Figure 1 is an-elevation of a portion of theoutside of one side of a box-car equipped with lay-improved grain door,the latter being shown in its closed pos1t-1on;.F-1g. 21s a -fragmentalview, in

- plan, of this partof the car and closed door as shown in said Fig. l,but with parts removed; Fig. 3 is an enlarged fragmentary view of saiddoor and the movable closurefor the crevice between one side edge of thedoor and the casing jamb; Fig. at is a like view to that given in saidFig. l, but showing the door shifted away from the-doorcasing opening;Fig. 5, like Fig. 2 1s a frag- 'mental plan view of the parts shown inFig.

at, with parts removed or sectioned away; Fig. 6 is a rear elevation ofthe door and its casing; 'Fig. 7 is an enlarged detail plan View of themovably-connected fixed and movable rails and the mechanism forreleasably holding the movabl rail: Fig. 8- is an elevation of partsshown in said Fig. 7, with the lower anti-friction bearing and guiderail, and showingthe door after its opening movement has commenced;-Fig.9 is a plan view similar to Fig. 7, but showing the moving'parts in anintermediate position, and Fig. 10 is a like view, showing these partsin their final positions; Fig. 11 is an elevation of the parts shown inFig. 10, showing theca'm completely rotated; Fig. 12 is a transversevertical section taken on the broken line 12-12 of Fig. 10,'and lookingin the direction indicated by the arrow.

In the drawings, similar numerals of reference denote correspondingparts throughout the several views.

The numeral 1 denotes a railway box-car having a door-casing 2, whoseopening may be closed by a door at, the latter being movably supportedsis-follows. a I

On the outside of the door-casing, over its opening, is supported atrack-rail 22, preferabl'y a Z-bar in cross-section, while on theoutside of th car, at the same height, is bracketed a spaced fixedtrack-rail 23, the

' rail 22 being bodily translatable to or from the car, so that one ofits ends may be i brought to abut uponf an end of the fixed rail toplacethe two rails in longitudinal ahnement. A fixed bracket 28 on the car,as shown-in Fig. 5, has a longitudinalslot 29 to receive a bolt 30 whichalso passes through an end of the rail 22, the bolt being slidable insaid slot, when the rail 22 is shifted outwardly away from the car 1.Another bracket i-l is fixed on said car at the opposite side of thedoor-casing :2. and has a horizontal part 45 provided with alongitudinal slot 50 through which extends a depending T-head lug 51,shown in Fig. 8, to disconnectibly and nlovably connect the other end ofthe rail '22, here denuded of part of its lower flange, to said bracket.The adjacent end'of the fixed rail 23 is secured to the outer extremityof the l) acket ll, and has its enddenuded of part of its web and uppervertical flange over said slot. Another bracket 32 supports the otherend of the rail 23.

The door i has its edges preferably seated andextendcd into rabbetedgrooves 3 in the adjacent parts of the door-casing. to serve as stopsand closing-1neans.- Thedoor has a pair of erect hooked bars 2-l securedto its upper part on spacing block to serve as hangers, in each of whichare alined'orifices to receive the pintles of rollers which -roll alongthe upper flat parts of the rails 22 and 23! -As shown in said Fi when Ithe door is seated or closed within the doorcasing '2, the rail 22 isshifted'bodi'ly inwardlytoward' and'nearly in contact with theouter-face of the ca l, being thus con- ,siderably'ofiset fromand out ofalinement with the fixed rail 23.

nally along said rails.

Referringnow to said Figs. 7 to 11 inclusive, the numeral 32 denotes abracketedshelf fixed on the side of the car 1, said shelf having thelongitudinal edge of cam form, and having a roller 52 rotatably imountedon "a stud thereon to extend slightly beyond ts edge. This shelfunderlies the horizontal slotted bracket 45, spaced therefrom, and iscut away at the rear sufficiently to seat it above the depending vbracket part 44 as, also over the depending part of a smaller bracket46, the horizontal.

part of the latter resting across the shelf 32,-

an'diboth orificedin line with the orifice in thefloverhanging bracketpart as, said 'a-l'ined OIlfKZGS receiving a short rock-shaft 4-2 onwhose upper end above the bracket 4:5 is.

fixedly mounted a cam 38 having a reentrant recess ll intermediatebetween a curved part '33" and aflattened part 48, the latter beingundercut, as shown in F ig. 11 Between the brackets and 3-2 and overlyinthe bracket part 47 of the bracket 46, a bifiircated arm 4.8 isfixed onthe rock-shaft 4:2 to extend horizontally; therefrom and has a roller 49rotatably mounted between its forks.

ea go -"-of the I elinevl bearing for the door When the (100114: isseated in the rabbets 3 of; the casing'2 ,the extended part-54 of themovable rail 22 extends slightly behind the flattened part &3 of saidcamj VVl1'en the door. is and the rail 22 are moved together outwardly,the end 545 of the rail rocksthe cam, its'shaft 4'2and' the arm 48,having entered the recess 41 of the cam 33. When the door'4 isshifted'longitudipally to the right on the now alined rails 22-23, itcontacts with and rides upon the "roller 49 in ,said arm 48, thusholding the cam 33 fast against the movable ra-il'22 atits end part 5-1tojlock the rails 22-23 in alinemen-t. The rails are thus retained infixed alinement until the door is shifted back to the left to releasesaid rollerji9.

In the operation of translating the door and movable'railoutwardly, asabove described, the roller 52 bears agamst the inner facehof the'doorwhile being moved to the anti-friction bearing, the cam ri'rht, as an II I I shelf 32 also acting as an 1nitS; further progress to the right. Alike bracketed shelf 56 fixed on the car below the shelf 3'2 carries arotatable. roller 57, asshown' in- Fig. 8, which'likewise acts as ananti-fric-. tion bearing for the lower part of said door while thelatter -'is being translated to the the door engages these sloping armsand is pushed inwardly to its seat in the door-casing. While this isbeing effected, the extended part 54 of the rail rocks the cam 33 itsedge passing into the recess 4:1, and the arm 48 rocking to its firstposit-ion. I have shown in said Figs. 1 and 3, fasteningmeans andcrevice-closures for said door when the door is seated in thedoor-casing rabbets 3.

The numeral 39 denotes a flat bar-,or which may be an angle-bar,positioned vertically alongside the T-iron side-plate 9 of said door andhung on hinges 37 having extensions or hasps 38. On said door in linewith said hasps are plates 34 having paired lugs 35 to receive the haspsbetween them, the -lugs being orificed to receive split-keys 36 tofasten the hasps releasably to the lugs, when the bars or angles 39 areswung over to cover the-crevices between vthe door-casings and theT-iron9, and also overlie the plates 9 to secure the door inplace in its seat.lhe T-irons 9 .seal the ra'bbetcrevice 40 between the door edge and thejamb-Q.

The crevices are thus sealed, and exit of small grain avoided. v Certainof these closures 39 may be dispensed with when desired, as indicated inFigs. 4 and 5, and other fastening, means employed without departingfrom the principle of my invention,

A swinging door or grain-outlet 6 is provided in the lower part of thedoors, hinged thereto and operated by means of lever-arms 7 ondouble-joint hinges, to simultaneously lift and swing outwardly'saiddoor, but this feature is not claimed herein, being specificallyclaimed in a pendingapplication for patent.

It will be observeld that in my improved device, the grain door-issuspended outside of the car, is translatable longitudinally therealong,and that there are noparts extending into the interior of the car to 0b-;stri'lct loading thereof. 4

Having described my invention, what I 1 claim as new, and desire tosecure by Letters the fixed rail when the door is being shifted from oneto the other.
